Why should aluminum metal polish be avoided on anodized aluminum surfaces?

Aluminum metal polish should be avoided on anodized aluminum surfaces primarily because it removes the oxide coat. Anodization is a process that enhances the natural oxide layer on aluminum, providing increased corrosion resistance and improved surface durability. The anodized layer is thicker than the natural oxide, and its removal compromises the protective qualities of the aluminum. By using a polish that abrades the surface, you strip away this important layer, exposing the underlying aluminum to corrosion and other environmental factors. A polished anodized surface may also lose its distinctive appearance and finish, which is specifically designed for both aesthetics and protection.
